3, tensile strength (fracture strength) is than carbon steel core lead (using the HC steel of about 210ksi) high about 150 percent.
4, the conductibility of compound reinforcement conductor is than the ACSR conductor height at least percent 40 of same outer diameter as, and has high 200 percent the desired value of ACSR conductor than same outer diameter as.
5, the CRAC conductor can also adopt T﹠amp; The D annex and with to conventional wire cable in other annex of installing of similar mode.
6, the CRAC cable has with on-the-spot erection unit that has minimal modifications and ability that process is used.
7, composite material can be compatible mutually with traditional lead and cable treatment technology.
8, the CRAC cable has been eliminated the eddy current heating.
9, compare with gauge wire, real aluminium core has the radial temperature difference of 1/100 degree.
10, in CRAC, there is not loss of strength, and the sagging increase that does not therefore have the annealing owing to tensional element to cause.
11, CRAC has the manufacturing requirement of simplification, because needn't need the stranded aluminium of multilayer in order to eliminate self-induction.
12, when using CRAC, owing to self-induction has been eliminated uneven electric current.
Except other advantage, what new CRAC conductor of the present utility model had the twice that is at least ACSR utilizes validity again.The existence of this new CRAC and commercial manufacturing process make it possible to be used in combination the stranded and compound pultrusion of wire squeezes (pultrusion) technology in continuous high speed, low cost, batch process assembly line.This technology also by making and integrated light composite material stiffener and be used for transfer of data and the optical fiber of intellectual monitoring, is transformed into high value-added product with aluminium.
